Manufacturing Process & Heat Treatment of Duplex S32205 Flanges
Annealing
Annealing of Duplex S32205 flanges is performed to relieve internal stresses and improve ductility. The flanges are heated to a temperature of approximately 1020°C to 1100°C and then allowed to cool slowly in air. This process enhances the material's toughness and reduces hardness, making it more workable for further manufacturing processes.
Forging
The forging process for Duplex S32205 involves heating the material to around 1150°C and then mechanically shaping it using hammers or presses. This process refines the grain structure, increases strength, and ensures uniformity in the material's properties. Forged flanges exhibit superior mechanical characteristics compared to those produced through casting.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Eliminate residual stresses from machining |
The combination of these processes ensures that Duplex S32205 flanges achieve optimal mechanical properties, making them suitable for demanding applications in various industrial sectors.
